Window cleaner program, software, and system — what should you choose in 2026?

Most window cleaners start with a spreadsheet, a calendar, and a good memory. It works — until it doesn’t. Suddenly you have 80 regular customers, three employees, and a pile of unsent invoices. This is where a dedicated window cleaning program makes a real difference. But which one should you choose?

We’ve gathered the most popular programs in Denmark and put them side by side, so you can make an informed choice.

Vinduespudser-program, software, and system — what's the difference?

In practice, there is no real difference. Danish window cleaners use the three terms synonymously when looking for a software solution for their business. 'Vinduespudser-program' is the classic term and covers the whole category. 'Vinduespudser-software' is a slightly more technical term for the same thing. 'Vinduespudser-system' is typically used when emphasizing that it's an integrated, all-in-one solution — with customer database, route management, invoicing, and communication in one package.

When this guide says 'vinduespudserprogram', it means the same as vinduespudser-software and vinduespudser-system. We compare the most popular choices in Denmark below, so you can see which one fits your business best — regardless of which of the three terms you happen to use.

What should a good window cleaning program do?

Whether you’re a solo operator or have a team, there are a handful of features that distinguish a proper window cleaning program from a generic solution:

Route planning — Your day is built around routes. A good program helps you plan the shortest path between your jobs, so you spend less time behind the wheel and more time on the ladder.

Customer cards and subscription management — Regular customers with recurring visits are the backbone of most window cleaning businesses. You need a place where you can see history, notes, prices, and the next scheduled date for each customer.

Invoicing — The ability to send an invoice right after a completed job — preferably with integration to your accounting software — saves you hours of manual work every month.

Mobile app — You’re not at the office. You’re out in the field. A program without a solid mobile app is essentially useless for a window cleaner.

SMS reminders — Automatic messages to customers before a visit reduce “not home” situations and make your day more predictable.

Software overview

Here are the programs that come up most often when Danish window cleaners talk software. We’ve tried to give an honest picture of each one.

Fenster — One of the most established programs in the industry, used by many small window cleaning businesses in Denmark. Fenster focuses on customer management, route display, and integration with Dinero for invoicing. With over 250 reviews on Trustpilot, it’s clearly the most tried-and-tested choice. Its strength is simplicity — it’s built specifically for window cleaners and doesn’t try to be everything for everyone. The limitation is that route optimization is manual, and the platform visually feels somewhat dated compared to newer solutions.

SkvizBiz — SkvizBiz stands out by having integrated accounting directly in the platform, so you don’t need an external accounting program. This can be an advantage if you want to keep everything in one place. The program covers customer cards, task management, and invoicing. The UX is functional, but the design feels somewhat older, and there are fewer automations compared to newer platforms.

Clientflow — Clientflow is newer on the market and built as an all-in-one platform for service businesses — including window cleaners. It includes AI-powered route optimization, GPS tracking of employees, a dedicated mobile app for the field, and automatic invoicing with integration to Dinero and Billy. Pricing starts at 199 DKK/month + 99 DKK per user with unlimited customers, and the platform scales from solo operators to businesses with 50+ employees. Its strength is automation and a modern interface. The limitation is that it's a newer platform and therefore has fewer reviews than established players.

Other programs — Beyond the three above, there are a number of smaller and more niche solutions. Lokal Vinduespudser offers a simple solution from 150 DKK/month, primarily aimed at solo operators. VintripDK, DoWipeIt, and Pudserprogram.dk also come up in conversations among window cleaners, but typically have fewer features and less online documentation. If you’re considering one of these programs, we recommend testing it thoroughly before committing.

Comparison

Which program fits you?

Choose Fenster if you’re a small business with few employees, you already use Dinero, and you want a proven system with a large community.

Choose SkvizBiz if you want to avoid a separate accounting program and prefer to have everything — including bookkeeping — in one place.

Choose Clientflow if you want automated route optimization, GPS tracking, a strong mobile app, and the ability to scale without switching platforms.

Choose Lokal Vinduespudser if you’re a solo operator, have a limited budget, and only need the basics.

Conclusion

There is no single program that’s best for everyone. The right choice depends on your business size, your needs, and your budget. But one thing is certain: continuing with spreadsheets and sticky notes costs you more than you think — in time, in revenue, and in oversight.
